6x9 in the front doors

6.5inches. Most modern speakers won't match up perfectly on the holes. I've owned a 1993 Mazda protege and a 1991 Mazda protege, I've changed the head unit, speakers and added an amp and sub to both, so I know =p
Front: 6x8x2.5" Rear: 6x8x2"
Per Crutchfield 6 by 8 in the front and 6 1/2 in the back door. Hope this helps
